FIGS. 1-10 depict a construction work machine 10 provided with a percussion work tool 15 according to one embodiment of the present invention. By way of example and not limitation, the construction work machine 10 may be a skid steer loader, as shown; however, in alternative embodiments, a variety of construction work machines may be provided with the percussion work tool 15, including, but not limited to, excavators or a loaders, for example.
Those of ordinary skill in the art will appreciate that the percussion work tool 15 is operated by the construction work machine and is preferably adjustably oriented relative to the construction work machine 10 via at least one actuator on the construction work machine 10, an example of which is illustrated at 20. Those of ordinary skill in the art will also appreciate that the at least one actuators are typically hydraulic actuators typically controlled by an operator of the construction work machine 10 in order to lift, lower, and rotate the percussion work tool 15 relative to the construction work machine 10.
According to one aspect of the present embodiment, the percussion work tool 15 is configured to impact and/or fracture a variety of materials, such as, for example, and not limitation, stone, concrete, and building materials. While especially suited for hardened materials, the percussion work tool may also impact and/or fracture relatively softer materials, such as earth, asphalt, gravel, or aggregate. In the present embodiment percussion work tool 15 is commonly referred to as a hydraulic breaker, hammer, or hoe ram.
As shown, the percussion work tool 15 is provided with a percussive force generator
24 and a bit 25 provided with a longitudinal length L and a tip 25 a. According to another aspect of the present embodiment, the percussive force generator 24 is adapted to drive the bit
25 in a substantially reciprocating fashion in the direction of the longitudinal length L of the bit 25 in order to assist the bit 25 and tip 25a with fracturing materials D. Those of ordinary skill in the art will appreciate that the percussive force generator 24 may be any mechanism capable of driving the bit 25 in a substantially reciprocating fashion in the direction of the longitudinal length L of the bit 25, including, but not limited to hydraulic or pneumatic ram or vibration generator.
According to another aspect of the present embodiment, the percussion work tool 15 is configured to pick up and relocate materials, including, but not limited to impact and/or fractured materials D. As shown, the percussion work tool 15 of the present embodiment is further provided with a gripper 30. As shown in FIGS. 2A-2B, the gripper 30 is adjustably oriented relative to the bit 25 via operation of at least one actuators, an example of which is illustrated at 31, whereby the gripper 30 is adapted to selectively open and close with respect to the bit 25 so that the gripper 30 and bit 25 may cooperate to hold and carry material D located between the gripper 30 and the bit 25. Advantageously, the percussive force generator 24 may selectively drive the bit 25, such as, for example, via actuation of a switch (not shown), when the gripper 30 and bit 25 cooperate to hold and carry material D.
According to one aspect of the present embodiment, the percussion work tool 15 may be provided a plurality of operable configurations, such as, for example, Ml and M2, shown in FIGS. 1 and 7. According to still yet a further aspect of the present embodiment, as shown in FIGS. 1 and 7, the percussion work tool 15 may be provided with a first mounting interface 50 that is adapted to cooperate with the construction work machine 10 to provide the first operable configuration Ml and a second mounting interface 51 that is adapted to cooperate with the construction work machine 10 to provide the second operable
configuration M2. As shown the first and second mounting interfaces 50, 51 may selectively couple to a mounting interface 11 on the construction work machine 10. As shown in FIGS. 4-7, the construction work machine 10 may transition from the first operable configuration Ml to the second operable configuration M2 by rotating the percussion work tool 15 so that the tip 25 a extends towards the construction work machine 10, disconnecting the first mounting interface 50 from the mounting interface 11 on the construction work machine 10, and connecting the second mounting interface 51 to the mounting interface 11 on the construction work machine 10.
The coupling between the mounting interface 1 1 and mounting interface 50 or, alternatively, mounting interface 11 and mounting interface 51 , if desired may be a quick connection, such as, for example, and not limitation ISO 24410 SSL. As shown by a comparison of FIGS. 1 and 7, advantageously, the first and second mounting interfaces 50, 51 may be adapted so that the orientation of the bit 25 and the gripper 30 relative to the construction work machine 10 differ when in the first operable configuration Ml compared to the second operable configuration M2.
As shown in FIGS. 1, 3-10, the bit 25 may take the form of a shaft, however, within the scope of the present embodiment, as shown in FIGS. 2A, 2B, 11, and 12, the bit 25 may be provided with a variety of shapes, within the scope of the present embodiment, and may, for example, and not limitation, include a blade implement 25c, for root cutting, for example, as shown in FIGS. 2A, 2B, 1 1, and 12, may include multiple tips 25a, 25b, as shown in FIG 12, or may include a replaceable tooth at the tip, similar to those mounted on buckets.

7. The method for providing a percussive work tool for a construction work machine according to claim 6, wherein the percussive force generator is adapted to selectively drive the bit.
8. The method for providing a percussive work tool for a construction work machine according to claim 6, further comprising the steps of:
providing a first mounting interface that is adapted to selectively cooperate with the construction work machine to provide a first operable configuration and a second mounting interface that is adapted to cooperate with the construction work machine to provide a second operable configuration, wherein the orientation of the bit and the gripper relative to the construction work machine differ when in the first operable configuration compared to the second operable configuration.
9. A method for operating a percussive work tool that includes a percussive force generator, at least one actuator, a bit provided with a longitudinal length, and a gripper and that is located on a construction work machine provided with at least one actuator, comprising the steps of:
using the at least one actuator on the construction work machine to adjustably oriented the percussive work tool relative to the construction work machine;
using the percussive force generator to drive the bit in a substantially reciprocating fashion in the direction of the longitudinal length of the bit; and
using the at least one actuator on the percussive work tool to adjustably oriented the gripper relative to the bit so that the gripper selectively opens and closes with respect to the bit.
10. The method for operating the percussive work tool according to claim 9, wherein the step of using the percussive force generator to drive the bit in the substantially reciprocating fashion in the direction of the longitudinal length of the bit assists the bit with fracturing or impacting materials.
1 1. The method for operating the percussive work tool according to claim 9, wherein the step of using the using the at least one actuator on the percussive work tool to adjustably oriented the gripper relative to the bit so that the gripper selectively opens and closes with respect to the bit further includes the step of using the gripper and bit to hold and carry material located between the gripper and the bit.
12. The method for operating the percussive work tool according to claim 9, wherein the step of using the percussive force generator to drive the bit in the substantially reciprocating fashion in the direction of the longitudinal length of the bit includes the step of selectively driving the bit.
13. The method for operating the percussive work tool according to claim 9, wherein the percussive work tool is provide with a first mounting interface adapted to provide a first operable configuration and a second mounting interface adapted to provide a second operable configuration, wherein the orientation of the bit and the gripper relative to the construction work machine differ when in the first operable configuration compared to the second operable configuration.
